To be honest Bronies are really happy peaceful people like Buddhists and I used to be a richard to them but now I'm not. Its just the Bronies that take their stuff to far, that's the awful part of the fandom. Other than that they are actually pretty nice people in my perspective, I mean I'm not a brony but they are pretty nice people.
Fnaf fan's are a bit of a problem since they turn stuff upside down, they are not tolerable at all. Most of the Fnaf fan's are all people that follow famous youtubers, it's pretty interesting how one person plays something and then a quarter of the world's population erupts.
Sonic the hedgehog fans are the worst, from my perspective some of them are a richard to me for no reason. most of it is all handicapped ms.paint .jepeg art with no effort at all. I just can't tolerate them at all
Furry's are okay but I know nothing about them other then them cosplaying in area's and drawing rather good art
Anime fans are really good artists, nothing wrong with them other than the ones that take it too far.
